The 'Bad Teacher' star posted her first tweet on the micro-blogging site today (08.11.13) and attracted 67,000 followers in just three hours.

Using the Twitter handle @CameronDiaz, the 41-year-old actress poked fun at her late arrival to the social networking site in her first post, writing: ''I JUST got a super cool new app called Twitter. Twelloooo!!! (sic)''

The actress' profile includes a brief bio that reads: ''Liver and lover of life; professional laugher, eater, make-believer.''

She also opted to use a quirky avatar picture, in which she appears wide-eyed and has her mouth open.
